The author demonstrates heuristic ways to differentiate healthy from pathological meanings in life. He argues that no one can tackle such a task without first detecting the purpose of life. To find it, one must recognize that, ultimately, life does not belong to anyone, and this on two accounts: First, it is received through parental union, and second, it is only temporal and must thus be "given back." Life is a loan that must be returned through death. These two polar realities, it is here believed, inform the whole of existence and guide us toward healthy growth (positive existential mental health).
